German authorities have announced that the flight data recorder of the TU-154 has been found.
They also have gone further in their official accounts of the events leading up to the mid-air collision.
Ulrich Müller, the Baden-Württemberg Transport Minister, has confirmed that the unsuccessful attempts by Swiss ATC (who are responsible for this sector despite its being over German territory) to direct one of the a/c to a lower FL were, in fact, addressed to the crew of the TU-154.
